tion to provide a device of this character by the use of which theconnecting blocks may be fastened securely to a'wall without thenecessity of using screws and by the mere punching of a hole in the wallof the proper size to receive the connectlng block.

It is also a purpose of this invention to provide a device of thischaracter in which, Whenever it is necessary to do so, the connectingblock may be detached from the casmg upon which it is secured, forpurposes of p I bers 15 and 16, which aresubstantially the repair.

Other objects and advantages of the in vention will appear as thedescription pro-" coeds, in connection with the accompanying drawings,wherein the preferred form of the invention 1s shown. It is obvlous,however, that various modifications may be made" from the exact detailsshown and described, and it is to be understood that I intend to availmyself of all such modifications as will Fig. 2 is a section on the line2-2 of Fig. 1; and

Fig. 3 is a section taken through the casing, showing the connectingblock partially inserted in the holding means.

Referring now in detail to the drawings, there is shown at 5 a portionof a wall, which may be the wall of a radio cabinet or power unit case,and which wall, as is common in present practice, is constructed of arelatively thin metal construction. 1 The material of the wall, however,is not important to the present invention, as our improved securing.

means is applicableequally well to various types of casings. The wall,as shown, is cut outto provlde a rectangular aperture 6 conforming insuch as indicated at 13 and 14 therein.

shape to'the top 70f the socket portion of the connecting block. Thisconnecting block, as shown, has longitudinal ridges 8iand 9 extendinglengthwise thereof at a 'short'distance' below the top 7 This connectingblock, of course, has terminals, as indicated at 10 and 11, forconnection to'the electrical apparatus within thecasing, andco-opera-tes withthe plugportion 12, having terminals The details ofthis connecting plug form aseparate application filed March 11, 1929, byHoward'B. Jones, and bearing Serial No.

Now the means for securing the socket portion of the connecting block tothe wall 5 consists of a pair of elongated spring memlength of theaperture provided at-6 in the wall 5. Thesespring 'members 15 and 16.are bent, as shown at 17 and 18,--to--form grooves fitting overopposite edges of the aperture 6. The spring members are'then curveddownwardly and inwardly, as shown clearly at 19 and 20, and are providedwith the upturned edges 21 and 22 which press against the lower edges ofthe ridges 8 and 9, as shown more clearly in Fig. 3. At the oppositeends of the members 15 and 16,

these edges'2 1and 22 may be cut away slightly so as to'facilitate theinsertion of the block there'between, but this, of course, is notnecessary in all cases.

Now, in mounting the block in position,

the members 15'and 16 are first fitted in position, as shown in Fig. 3,and then the block is inserted between them at one end block is thenpressed along beneath the wall so that the edges 21 and 22 engage theunder sides of the ridgesS and 9 and tend to press the block upwardlyagainst the wall 5. The

by sliding it relative to the members 15 and V .16 until it aligns withthe opening 6, and, when the block is in suitable alignment with theopening 6, the resiliency of the members 15 and 16.willv force the blockupwardlyinto the position shownin Fig. 2, so thatthe portion 7 thereofis substantially flush with the tops of thebent portions 17 and, 18onthe members '15 and 16. p x

' The block is now mounted in position for permanent use,"si'nce itcannot'slide endwise due to the projection ofthe portion 7 up- "theportion? below the level of thewall and then sliding the blockendWise-out of engageinentwith the spring members and16. c From theabovedescription, itis thought that theconstruction and advantages ofthis l Letters Patent 1s device will be clear tothose skilled in this i;art,,andihaving thus described our invention,
